Large isotropic negative thermal expansion above a structural quantum phase transition
(2015-10-01)
Perovskite structured materials contain myriad tunable ordered phases of electronic and magnetic origin with proven technological importance and strong promise for a variety of energy solutions. An always-contributing ...
The Josephson junction as a quantum engine
(2023-11-10)
We treat the Cooper pairs in the superconducting electrodes of a Josephson junction (JJ) as an open system, coupled via Andreev scattering to external baths of electrons. The disequilibrium between the baths generates the ...
QA Programme of the TLD laboratory of the University of Costa Rica: IEC 61066 testing
(2008)
The Thermoluminescence Personal Dosimetry Laboratory of the University of Costa Rica provides dose measurements for around 90% of occupational radiation workers in the country. The assessment of doses to workers routinely ...
Phototransport Properties of a-SiC:H Alloys
(1995)
We report a study of the mobility-lifetime products of the two charge carriers in a-SiC:H alloys. The measurements were carried out as a function of the carbon concentration and the temperature. An analysis, relying on the ...
Evaluation of [18F] FNM biodistribution and dosimetry based on whole-body PET imaging of rats
(2018)
Introduction: The aim of this work was to study the biodistribution, metabolism and radiation dosimetry of rats
injected with [18F]FNM using PET/CT images. This novel radiotracer targeting NMDA receptor has potential ...
Probing the origin of 4FGL J0822.8–4207: cosmic ray illumination from the SNR Puppis A and the Herbig-Haro object HH219
(2021)
4FGL J0822.8–4207 is a point source found in the 4FGL-DR2 catalogue by the gamma-ray observatory Fermi-LAT and has no known association. We carry out X-ray observations of 4FGL J0822.8–4207 to help understand its nature. ...
Implementation of patient dosimetry in the clinical practice after targeted radiotherapy using [177Lu-[DOTATO,Tyr3]-octreotate
(2018-11-29)
Background: This study’s aim was to develop our dosimetric methodology using a commercial workstation for the
routine evaluation of the organs at risk during peptide receptor radionuclide therapy (PRRT) with 177Lu.
Methods: ...
Relation between Luminescence and Electronic Surface Characteristics in p-type Porous Silicon
(1997)
Measurements of photoluminescence, electronic surface states and effective surface area, at various stages of the anodization process, are presented. The results show a behavior different from that observed on n-type porous Si.
Biological and dosimetric evaluation of [11C]S-adenosyl methionine as a potential agent for prostate cancer diagnosis
(2018)
Introduction: [11C]Choline ([11C]COL) has been widely used for prostate cancer diagnosis; however, this
radiopharmaceutical is not recommended for patients with a low absolute PSA value (< 1 ng/mL) due to its
limited ...
